Saw this girl for the first time, giving presentation on the last day of class.

Never had opportunity to talk to her because I had no clue she was in my class, but I found her instagram, followed, and she followed back. She no doubt recognized me from class.

I am maybe once or twice a year attracted to a girl on this level so I have to send it deep or go home trying.

How do I dm her effectively? I never do dm because I usually get the chance to escalate in person. I just need to secure a date, I have super high success rate in person. My instagram is mediocre and for that reason I never dm.

How to go I from instagram to date in this context?
